Claim of US Patent No. 9,770,811

1. A ratcheting tool for driving a socket, the ratcheting tool comprising:
a body having a head that defines a cavity and having an elongated handle extending away from the head;
a ratchet member comprising an annular ratchet portion disposed in the cavity so that the ratchet portion is rotatable about
an axis and a drive tang extending from the ratchet portion externally of the body and so that the drive tang rotates with
the ratchet portion about the axis;

a pawl disposed in the body in communication with the ratchet portion selectively between
a first position in which the pawl transmits torque from the body to the ratchet portion in a first rotational direction with
respect to the axis and ratchets with respect to the ratchet portion in response to torque from the body in a second rotational
direction with respect to the axis opposite the first direction, and

a second position in which the pawl transmits torque from the body to the ratchet portion in the second rotational direction
and ratchets with respect to the ratchet portion in response to torque from the body in the first rotational direction;

a detent disposed in the drive tang so that the detent is reciprocally movable in a direction transverse to the axis between
a first position and a second position, wherein the first position of the detent extends further from the axis than does the
second position of the detent;

a linkage extending through the drive tang to engagement with the detent, wherein the linkage is accessible at a surface of
the ratcheting tool, wherein the linkage engages the detent so that when the linkage is in a first position, the detent is
in its first position and so that actuation of the linkage to a second position causes the linkage to move the detent to its
second position; and

a locking element that defines a flange and that is attached to the ratchet member pivotally about an axis that is offset
from the ratchet portion axis and that passes through the ratchet portion, the locking element being pivotal between a first
position wherein the flange engages a groove defined by the linkage when the linkage is in its first position so that the
locking element blocks the actuation of the linkage and a second position in which the flange disengages from the linkage
with respect to the locking element's first position.
